居民消费价格指数(CPI)作为衡量一国价格总水平的指标,其变动趋势必然会影响消费者的预期。存款准备金率作为一国中央银行货币政策的主要工具之一,其调控是否合理也深受老百姓关心。在我国目前CPI涨幅偏大、中央银行频繁调整存款准备金的现实情况下,这两者之间的内在联系值得研究。本文通过搜集相关数据,对这两者之间的变动规律进行实证研究。 As a measure of a country’s overall price level, the consumer price index (CPI) will inevitably affect consumers’ expectations. Deposit reserve ratio as a central bank monetary policy, one of the main tools, its regulation is also well received by the people concerned.
